Hi, I tried following thing:
@MappedSuperclass
@IdClass(FootballerPk.class)
public class Footballer {
String firstname;
String lastname;
//part of the id key
@Id public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
//part of the id key
@Id public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getClub() {
return club;
}
public void setClub(String club) {
this.club = club;
}
//appropriate equals() and hashCode() implementation
}
@Embeddable
public class FootballerPk implements Serializable {
String firstname;
String lastname;
//same name and type as in Footballer
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
//same name and type as in Footballer
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
//appropriate equals() and hashCode() implementation
}@Entity
@AttributeOverride( name="firstname", column = @Column(name="new_firstname") )
public class ExtendedFootballer extends Footballer{
...
}But I dont get it to work, that the Attrribute is overwritten.
All works fine if I dont use @IdClass.
Is this a possible Bug?
